Director, Head of Property Finance

TSP is a boutique, property and asset management business. We manage office, industrial and retail assets across the UK, creating spaces that are genuinely commute-worthy, hospitality-led, experience-driven, and proudly people-first.

We’re 17 years old, but we operate with the energy of a start-up: fast-moving, agile, and unafraid to challenge the status quo. Innovation, sustainability, and smart use of technology sit at the heart of what we do, helping us deliver healthy buildings filled with happy tenants.

Our culture is collaborative and entrepreneurial. We’re Investors in People Gold which puts us in the top 1% of companies in the UK and we were the UK’s first B Corp-certified real estate company. We are multi award winning and most recently, we were named Professional Services Team of the Year at Property Week Awards 2026.
